Using a rule to set a depth stop or countersink on a drill bit typically requires juggling all three items in one hand while tightening the hex key with the other. This gauge has a V-shaped cross section that helps center and align the bit on the gauge, making it far less awkward and frustrating to hold them together.

The 110° angle accommodates bits up to 1" in diameter. With Imperial and metric scales (graduated in 16ths and millimetres), the 3 1/4" aluminum gauge has an anodized finish and laser-etched markings for ease of reading.
